There was that problem with the skrewts so it is unclear if this is a run of the mill malfunction or if the one who must not be named is involved. The best wizards are working on it and if it can be resolved through magic they can supply what is necessary. In any case Hagrid is directing the recovery and I am sure Dumbledore will back him up if necessary. Not to worry McGonigal will supervise the operation.
Expect success in 2 - 3 months
